Why do people want to extract images from EPUB files?
Extracting images from EPUB files can be useful for various purposes. While it is very convenient to read EPUB files on various devices like eReaders, tablets, smartphones, and more, some people need to extract images from EPUB files, especially for ebook designers, researchers, or anyone who needs to get a better reading experience.
1. Archive and back up files: Extracting images can help you preserve the visual elements of a book, especially if you're concerned about potential changes to the EPUB file or the availability of the e-reader software.

Two methods to extract images from EPUB
Method 1: Unzip the EPUB file to extract images
EPUB is essentially a zipped archive that contains the various components of a digital book, including images, fonts, stylesheets, text, and metadata.
Rename the file extension of your EPUB file from .epub to .zip.
Extract the contents of the .zip file using a file archiver tool, like WinZip, 7-Zip, or other apps.
Inside the extracted folder, you will find a META-INF and OEBPS folder, and the images are typically stored in the OEBPS folder.
Finally, you can easily back up these image files and transfer them to other places.
Pros
